Adding Tiers to the Asset Package

[TSmith]

Got a question about adding tiers to a Utility Network. I believe I would have to convert an Asset Package to a UN, then add the tier, then go back to an asset package. 

Is there a supported workflow to add tiers or other network items to the asset package, prior to conversion? The "Add Tier" GP tool only takes a UN object as input.

Thanks for any pointers!

You can disable network topology and add a tier in the UN.  To add a tier in the Asset Package, you have to fill out all the tier properties, which can be a complicated process.

@TSmith - As far as I am aware that is the only way. You cannot create Tiers dierectly in a AP but you can in a UN. 
AP -> UN -> Add tiers  -> Export AP

You can create a temp UN in a mobileGDB to achieve this.

@TSmith, @gis_KIWI4 you can do it directly in the asset package. 

Here is a link to the asset package schema.

You'll need to add a row to the B_Tier table, then create a subnetwork definition for the tier by populating all the B_Subnetwork_* tables with the correct info.

Ideally you can model the subnetwork definition after an existing tier in your network. That is to say you can create duplicate rows in those tables from an existing tier, update the tier name to represent your new tier, then modify the properties you need.
